Thunalbene, a stilbene derivative from the orchid Thunia alba.[Reference: WebLink]

METHODS AND RESULTS:
Thunalbene, a new stilbene derivative, was isolated from the orchid Thunia alba which also afforded six known stilbenoids: batatasin-III, lusianthridin, 3,7-dihydroxy-2,4-dimethoxyphenanthrene, 3,7-dihydroxy-2,4,8-trimethoxyphenanthrene, cirrhopetalanthrin and flavanthrin.
CONCLUSIONS:
The structure of Thunalbene, the first stilbene derivative isolated so far from an Orchidaceae plant, was established as 3,3′-dihydroxy-5-methoxystilbene from spectral and chemical evidence.
